PROCESS OF MANUFACTURING COAL-HODS.

SPECIFICATION forming part of Letters Patent No. 377,705, dated Pebruary 7, 1888.

Application filed May 4, 1887. Serial No. 237,107. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD BARRATH, a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Processes of Manufacturing Coal-Hods, of which the following is a specification.

This invention has for its object to manufacture a coal-hod from a cone-shaped piece of metal and a shell, as hereinafter described, and specifically pointed out in the claims, reference being made to the accompanying drawings, in which- Figure 1 shows a blank from which the shell I of the hod is formed. Fig. 2 represents a blank for making the cone from which the bottom is formed by circumferential crimps. Fig. 3 represents the cone formed from the blank shown in Fig. 2. Fig. 4 is anelevation of the reduced cone formed by the first step. Fig. 5 is a sectional elevation of the base after the circumferential crimps have been formed. Fig. 6 is a section of the secondary die used inshaping the base. Fig. 7 is a sectional view of the shell. Fig. 8 is a sectional elevation illustrating the die employed to connect the shell to the base. Fig. 9 is a similar view to that of Fig. 8,, showing the die in an advanced position. Fig. 10 represents the dies in the act of closing dow'n and uniting the base and shell and compressing the crimps. Fig. 11 is a sectional View of the bucket completed. Fig. 12 represents one of the dies used in the preliminary forming of the crirnps. Fig. 13 is a section of the primary die.

A represents the shell of the bucket; A, the blank from which the shell is made.

B represents the base; B, the blank from which it is made.

C represents the cone to which the blank B is first formed.

D represents the base of the die, pierced with an orifice to receive the cylindrical stems E E of the movable dies F and G.

G represents the primary die, which is introduced into the base B (shown in Fig. 13) for the first step in the formation of the hod-base, and H represents the outside or shaping die, provided with a series of orifices, 1, 2, 3, 4,

The cone, by means of the die 11, is first" brought into the shape shown in full lines, Fig. 4, having a series of ledges formed in the following manner: The cone C is placed upon 7 manner the remaining orifices are employed to form the succeeding ledges c, d, and e. When the cone has been formed into this shape, die G is removed and the die F (shown in Fig. 6)

is inserted in its place and the base placed back over said die F. When the die His again brought into operation, the orifice 2. is brought down upon ledge b, forming a crimpof'said ledge.. The orifice 3 is brought down upon the ledge c, forming a second crimp, and this is continued until the several ledges, excepting the first, have been crimped down, when the base is in the form of crimps-shownin Fig. 8. Then the shell A of the bucket is placed over die E, with its hooked or turned over edge a resting against the ledge a of the circumferential base, which is placed as seen in Fig. 8. A shaping-die, I, is then introduced and brought down onto the ledge of the base, as shown in Fig. 8. Said die is provided upon its under side with an annular groove, 8,

adapted to receive the crimp X, which, owing to the double thickness of metal at this point, requires additional space between the dies. Said groove s leaves a shoulder, t, upon the peripherypf the die, which exerts a pressure upon'the part a of the base of the hod and crimps it securely around the bottom portion, 3 of the bottom of the hod. By applying pressure to the die I, the ledge a is buckled or turned around the hook-edge t. Fig. 9 shows the seam partly formed, and Fig. 10 shows the seam completed. The pressure of the die I closes the crimps together from the form shown in Fig. 8 to that shown in Fig. 10, which step completes the uniting of the base and shell and presses the crimps down so as to form a very solid and substantial water-tight bucket.

50 and 5, pierced therein. It' will be observed that the weight of the 10 contents of the hod resting upon these completed crimps tends to compress them more together, and does not tend to open out the metal, which would be the case if the crimps were formed from the same piece of metal which forms the shell of the hod.

The shape of the crimp after the hod is completed is shown in Fig. 10. The movement of making the seam and pressing down the crimps is illustrated in Figs. 8 and 9.

Having thus described my invention, what I claim is- 1. The method herein described of making a coal-hod, which consists in first shaping a piece of metal into a hollow cone, then forming a portion of the cone extending from its apex toward the base into a series of ledges of diflerent diameter, then crimping said ledges,
